ELECTRICALLY-CONTROLLED ELEVATOR.

SPECIFICATION forming part of Letters Patent No. 422,968, dated March11, 1890.

Application filed June 5, 1889. Serial No. 313,121. (No model.)

To all whom it may concern:

Be it known that I, VALTER J. PAINE, of Boston, county of Suifolk,Stateof Massachusetts, have invented an Improvement inElectrically-Controlled Elevators, of which the following description,in connection with the accompanying drawings, is a specification, likeletters and. figures on the drawings representing like parts.

This invention relates to a novel system for electrically controllingthe movement or travel of a car or carriage from one point or station toanother or distant point or station, and has for its object to providesuitable mechanism, as will be described, whereby the movement of thecar or carriage may be automatically controlled from any one of a seriesof stations or stopping points, and also, it so desired, from the caritself.

My invention is especially'adapted, among other things, to be applied onelevators of any usual or well-known construction, such as now commonlyin use; and, in order that my invention may be readily comprehended, Ishall specifically describe its operation when applied to an elevator.

In accordance with my invention the motor mechanism employed to raisethe elevato r-car, which mechanism may be of any usual construction, isgoverned, as herein shown, by two electro-magnets in an electric circuitextended through the elevator-car and provided with a manual switchcarried bythc ear to be operated by a person on the car, and with anautomatieally-operated switch also carried by the car and which isoperated outside the car at a predetermined point.

The operation of the automatically-operated switch may be controlled, aswill be described, either from within or on the car, and also from agiven station or point outsidethe said car as, for instance, at a floorof the building in which the elevator is located. At each station orfloor of the building is located a switch provided, as herein shown,with two contactpoints, one of which co-operates with a terminal of acircuit connected to the electro-magnets controlling the motormechanism, the other terminal being in circuit with an auxiliary magnetcontrolling a cam which, when in position, as will be described,actuates the automatically-opcrated switch on the car to break the mainline or circuit and stop the movement or travel of the car at thatstation or landing.

The circuit of the motor-operating magnets connected. to the switch atthe station or floor referred to has located in it a movablecircuitcontroller operated, as will be described, by a cam or projectioncarried by the car to control the circuit of one or the other of themain line magnets, so that when the switch at the floor or station isclosed the circuit of that one of the main-line magnets is closed whichwill. operate the motor mechanism to send the elevator-car to thestation or floor at which the said switch was closed.

The circuit of one of the main-line magnets is momentarily closed whenthe switch at the floor or station or on the car is closed, and thecontinuity of the magnet-circuits to operate the motor is maintained, aswill be described, even aft-er the switch at the floor or station isopened, the said main-line circuit being maintained closed untilpositively opened either by a manual switch or by the automatically-operated switch carried by the car.

My invention therefore consists, essentially, in the combination, with acar or carriage and a motor mechanism to cause the said car or carriageto travel, of a magnetic device operatively connected to the car orcarriage to control the operation of the motor mechanism from the car, amanual switch and an independent automatic switch earried by the car incircuit with the magnetic device, and a cam or projection in the path ofmovement of the car to operate the said automatic switch and stop thecar, substantially as will be described;

Other features of my invention will be pointed out in the claims at theend of this specification.

The elevator-car A, herein represented as a passenger-car provided withthe usual door A, is suspended in an elevator-well A by preferablymetallic or wire cables a a (t the cables to a being passed aboutsuitable sheaves at the top of the building and connected tocounterbalaneing-weights a and the cable a being passed about thesheaves at the top of the building and connected to a drum to, allsubstantially as with elevators as now commonly constructed.

The elevatorear A is raised by a motor mechanism, herein shown, of thatclass known as the belt system, consisting of a straight belt a passed,about a pulley a (see Fig. 2) on a driving-shaft a and about a similarpulley on-the shaft of of the drum a and of a cross-belt a on a pulley aon a shaft a in line with the shaft c the said cross-belt being passedabout a pulley e on the shaft a opposite to the pulley about which thebelt a is passed. The shaft a is provided with a fast pulley (L -311d aloose pulley a, and the shaft e is provided with a fast pulley a. Theloose pulley a, as shown in Fig. 2, is engaged by a belt (0", passedabout a drum or pulley a", on a shaft (4 connected by a belt a with apulley (L20 (see Fig. 1) on the crankshaft o? of the engine, the saidcrank-shaft being rotated through the connecting-rod (L22 and piston-roda of an engine a, which may be of any usual or desired construction. Theshaft (L18 is provided with a pulley Z), connected by a belt I) (seeFig. 2) with a pulley b on a shaft 1), having journals in suitablebearings Zr. (See Fig. 3.) The shaft is provided on opposite sides ofits center with a right and left screw-thread or worm ZN), with whichco-operate pallets or fingers D b on opposite ends of an armaturecarrying bar U,

pivoted, as at b to a casting or plate Z2 secured to or forming part oftwo sets of electromagnets Z9 b, each set of magnets, as herein shown,comprising two magnet-coils.

Each magnet-coil, as herein shown, has its front pole-piece extendedbeyond the face of the magnet, and the said pole-pieces have cooperatingwith them armatures b b", secured to or forming part of the bar Z)". Thearmatures 11 Z) are normally held away from their pole-pieces, as hereinshown, by a spring Z2", (see Fig. 3,) acting on the bar I). The coils ofthe magnets b b are wound continuously, and one end of the wires of thesaid magnets are joined together and, as herein shown, connected to onepole of the battery 13 (see Fig. 1) by wire I), the said wire, as shown,being connected to the negative pole of the battery B. The opposite endof each wire of the magnets is grounded or connected to the yokes orcross-bars b If, connecting the cores of the said magnets. (See Figs. 1and 5.)

The positive pole of thebattery is connected by wire 0, as shown in Fig.1, to the shaft a and the circuit from the shaft a to the ele- Vator-carmay be traced through the metallic drum a and wire cable or rope a tothe bolt 0' on the elevator-ear and from the bolt 0 by wire 0 to oneportion or section 0 of the metallic rail, upon which run the metallicwheels 0 c of the car-door, as clearly shown in Fig. 7.

The electrical circuit through the rail referred to isbroken,preferably, by a piece a of insulation interposed between thesections 0 and c of the said rail, the circuit-from the rail-section 0"across the insulation e being traced through the wheel 0" to wheel 0 ofthe door by wire 0 connecting said wheels.

The railsection c" has connected to it a wire 0 having its other endconnected to a spring-arm c, secured, at 0 (see Fig. 6,) to the bottomof the car and having its free end normally engaged by a spring-actuatedpawl 0 on a bar 0 carried by a lever c, pivoted to the bottom of thecar, the bar a being provided at its outer end with a roller 0, for apurpose as will be described.

The spring-arm e constitutes one member of an automatically-operatedswitch, the cooperating member of which is herein shown as an arm 0secured to the bottom of the car, as by screws 0 which also secure tothe car a second arm e extended substantially at right angles to the'arm 0 and substantially in line with the pawl c the end of the arm 0being beveled or inclined to engage the rounded or inclined part of thepawl a to to the bolt 0 to which the wire cable a is se- The wire cablea is connectedby wire on red.

Down, and shown as two contact-pieces secured to or forming part of apointer or selecting-bar d, Fig. 8, fast on an arbor (1 pro-.

vided with a bevel-gear (1 Fig. 9, in mesh with a bevel-gear (Z on ashaft (1 extended below the car-floor. The arbor (Z has loose on it apreferably metallic bar (1 provided with a handle of insulatingmaterial, the said bar forming a common contact member for thecontact-pieces d d. The bar (Z is 0011- nected by wire (1 to the wire 0and the switch or contact-piece dis connected by wire (1 to a contactarm(1 secured to the car and in contact with va metallic bar or guide (1which is herein shownas broken at its upper end near the top of thebuilding and provided with a strip d" of insulating material, for apurpose to be described. The guide-bar c below the strip d is connectedby wire (I to the yoke or cross-bar If of the magnet b (marked in thedrawings the up magnet.) The switch. or contact member (1' is connectedby wired to a contact-arm d carried by the car and normally in. contactwith a guide-bar d on the opposite side of the elevator shaft or well,as shown in Fig. l. The guide-bar d is broken at its lower end or nearthe bottom of the elevator-well and electrically separated by the strip(1 of insulating material. The upper portion of the bar (Z is connectedby wire (1 to the yoke or cross-bar I) of the magnet 19 (marked in Fig.1 as the down magnet.) The selecting device or pointer d co-operateswith a series of numbers indicating the floors or landings of thebuildin g in which the elevator is located. The shaft (1, )referablybelow the car-floor, is provided with a segmental gear at, (see Fig. 6,)in mesh with a rack-bar e movable in suitable guides e secured to thecai floor. The rack-bar ef" has secured to or forming part of it aspring arm or extension e, secured to a rod or bar e provided'at one endwith a roller a, normally resting against the lever 0 the bar 6 at itsopposite end being provided, preferably, with a roller extended beyondthe side of the car. The bar 0 which is connected to the lever c, ispreferably surrounded by a spiral spring 0, which acts against suitableguides secured to the carfloor and against a collar on the said bar toforce the latter out into its normal position and bring the roller 0 onthe end of the said bar outside of the car.

The side wall of the elevator in which the doors of the dilferentlandings are located is provided at each landing, near the doorwaythereof, with a projection or stud f, (marked 1, 2, 3, and t in Fig.10,) with which co-operates the roller 6, as will be described.

The spring-arm c and its co-operating bar 0 constitute the automaticallyoperated switch carried by the elevator-car, as described, and theswitches (Z and d and also the car-door constitute manual switchescarried by the ear,

Vt ith the apparatus constructed as thus described the ascent anddescent of the elevator-car. may be controlled from within the elevatoras, for instance, let it be supposed that it is desired to ascend. Theoperator on the car closes the circuit of the up switch by moving thehandle of the bar (Z toward the left, as shown in Figs. 1 and 8, therebyclosing the circuit of the up magnet at the switch (1, which circuit maybe traced as follows: from the positive pole of the battery by wire 0,shaft a drum a, cable a to the bolt 0 on the car, and from the bolt 0'by wire 0 to the rail 0 thence by the wheel 0 wire 0", wheel 0 to therail 0 thence by wire 0 spring-arm 0", arm 0 wire 0 thence by branchwire d through the bar (Z a contact member of the switch cl, wire (1 tocontactarm (1 thence by guide-bar (1 wire (1 to the yoke Z2 of themagnet 19, through the coils of the said magnet to the negative pole ofthe battery by Wire 17 \Vhcn the up magnet ZP" becomes magnetized, thearmature t, Fig. 3, is attracted, and the bar I) is turned on its pivot,so as to bring the pallet or finger (2 into engagement with the worm b.'When the pallet b on the' armature carryin g bar I) is brought incontact with the worm Z), the said pallet is caused to travel or ismoved toward the right or in the direction of arrow 21, Figs. 2 and Asthe pallet Z2 is moved toward the right, it carries with it the castingb and the belt (6 which is engaged by pins 25. on the upper plate of,the casting b, the said plate having secured to or forming part it anarm 27, pivoted, as-at 28, (see Fig.2.) to across bar or frame 29. Asthe casting b is moved in the direction of arrow 21, the belt a isshipped from its loose pulley a 'to the fast pulley e which. is rotatedin the direction indicated by arrow thereon in Fi 2. As soon as the belta is brought into engagement with the fast pulley (0 the pulley e isrotated, and the belt a thereon made to travel in direction of arrow 30,Fig. 1.,thereby winding the drum min the direction of arrow 31 andhoisting the elevator. As soon as the armature b comes in contact withthe polepiece of the magnet b a circuit for the said magnet is completedthrough the bar b, as will be described, so that as soon as the operatorin the car has pressed the push-button or switch (1 to complete thecircuit he may immediately remove the pressureor break the circuit atthe switch d on the car. The

ITO

circuit of the up magnet is now broken on p be traced as follows: fromthe positive pole of the battery by wire 0, shaft a", drum (0, cable ato the car, wire 0 rail 0 wheel 0, wire 0 wheel a, rail 0 wire cspring-arm 0", arm 0 wire 0 to the bolt 0 thence by cable a, wire 0 andcontact-arm 0 guidebar c, and wire to the armature-carrying bar I),through the armature b core of the magnet I), then through the coils ofthemagnet and wire U to the negative pole of the battery.

The circuit of theup magnet just described will be maintained closed andthe car will continue to travel upward until the said circuit ispositively broken from the ear.

The circuit may be broken by one of the projectionsf on the wall of theelevatornvell, it acting on the roller a so as to force the said rollerand its bar outward, or in the direction of arrow 20, Fig. 0, and thusautomatically remove the spring-arm e from contact with the arm 0thereby breaking the said circuit at that point.

The operator on the car selects through the pointer (Z which projectionf shall break the cireuit-as, for instance, if he desires to go to thethird floor he turns his pointer or selecting device until it registerswith the number 3 on the dial indicating the third floor. As the pointer(Z is turned a bar (1' is also turned, and the shaft (1 is rotatedthrough the gears (Z (1 and the rack-bar 6"", through the segmental gear6, is moved along in its guides 6 until the roller 6 stands or isbrought in line with the projection f marked 3, which projection, as hasbeen stated, is so located with relation to the third landing that whenthe roller e meets the projection f marked 3 the door of theelevator-car will be substantially opposite the door on the landing.\Vhen the roller 2 is acted upon by the projection f marked 3 and thebar 6 is moved in the direction of arrow 20, the said bar acts on thelever 0 and moves the said lever and the bar 0 carried by it in thedirection of arrow 20, thereby carrying the spring-arm c away from itsco'operating contact-arm c and breaking the circuit of the up magnet atthat point, as described. As the bar 0 is moved in the direction ofarrow 20, the pawl c is moved outward by the inclined end of the arm aand is disengaged from the spring-arm 0", thus permitting the latter tofly back and again make electrical connection with the arms 0 closingthe cir cuit of the up magnet at that point. As soon as the spring-arm0' through the pawl 0 is removed from contact with its co-operatingcontact member a, the circuit of the up magnet is broken at that point,and the said magnet becomes demagnetized, thus permitting the spring I),Fig. 3, to center the armature-carrying bar I)" and remove the pallet Z1from engagement with the worm As soon as the pallet is moved fromengagement with the worm Z) the shipper-bar 27 is centered, as hereinshown, by means of a weight 32, connected by a cord 33 to the bar 27, asshown in dotted lines, Fig. 3, the-said cord passing under a pulley 34;and over a pulley 35. The elevator is now supposed to be stationary andopposite the third floor of the building, and if it is desired todescend the switch (1' will be closed, thus magnetizing the down magnet(J the circuit being traced as follows: from the the positive pole ofthe battery by wire 0, shaft a drum a, cable a wire 0 rail 0 wheels 0 a,rail 0 wire 0 through the automatic switch, wire 0 branch wire (1, wire(1, contact-arm (Z guide-bar (Z wire (1 to the yoke 11* of the magnet b,thence through the coils of the said magnet to the negative pole by wireI). As soon as the circuit of the down magnet is closed at the switch (1it attracts its armature 11 thereby engaging the pallet b with the wormI), which moves the shipper 27 in the direction opposite to thatindicated by arrow 21, Fig. 2, and brings the belt a into engagementwith the fast pulley (0 on the shaft a thereby producing rotation of thedrum a", through the belt a, in the direction of arrow i0, andpermitting the car to descend.

If it is desired to stop the car at any floor or landing below thethird, the bar (1 will be moved until the pointer (Z registers with thenumber indicating such floor, and the roller 6 will be thus placed in.position to be acted upon by the projection fat the selected floor, thesaid projection acting on the said roller to break the circuit of thedown magnet at the automatically-operatcd switch c" carried by the car.

In order that the travel of the elevator may be controlled from eachlanding of the building, I have provided at each landing a switch 75,provided with two contact-terminals 79' 75 which co-operate withcontact-terminals7t 7;". The contact-terminal has connected in circuitwith it an electro-magnet 7;, which is connected by wire it with thewire I), leading to the negative pole of the battery. Thecontact-terminal k is connected by wire 7: with a wire 70, having oneend connected to a guide bar or' red 7a, with which co-operates acontact member 7a joined by wire It to the cable a, which is connectedby a wire 7. to one terminal of a bell 7c of any ordinary construction,the other terminal of the said bell being connected by wire L to thewire 0 The contact-terminal 7c is connected by wire 73 to the wire 0 andthe contact-terminal 7& co-operating with the terminal is, is connected,as herein shown, by wire k to a cam'switch (herein shown as a pivotedrocker L located in a suitable case if, Figs. 17 and 18, in which themagnet k is placed. The rocker 73 is preferably provided with twospring-arms 75 73 which cooperate with pins or studs L k, Fig. 18,connected, respectively, by wires U If, Fig. 1, with the wires (Z and (ZThe rocker 7J co-operates with a projection on a leyer 7.3 Fig. 18,pivoted as ICC IIO

I as at 7c, and having an arm 7e constituting the armature for themagnet 70". The cam-- lever 75 is provided with two oppositely-in.-clined faces 36 37, with which co-operates the roller 0 Fig. 6, on thebar 0 carried by the elevator-car. The rocker 11: is acted upon by afixed roller or projection i (see Fig. 6,) which is carried by the car.

In order that the operation ofthe device on the landing maybe readilyunderstood, let it be supposed that the switch 7.: on the third,

landing (marked L in Figs. 1 and 10) has been closed, and that theelevator at such time is in the position indicated in Fig. 1. As soon asthe switch 7a is closed the circuit of the magnet k is closed, and thesaid magnet attracts its armature 70 and moves the lever is fromitsfull-line position in Fig. 17 out into its dotted-line position. Assoon as the switch 7a is closed the bell 7e carried by the car, is rung,its circuit being closed, which circuit may be traced as follows: fromthe positive pole of the battery by wire 0, shaft a drum a", cable awire 0 Wire 70 through the bell, wire 70 cable a, wire 70 contact memherIt guide-bar 7c", Wires k and k to contactterminal 70 through the magnet75, and thence by wire 76 and wire b to the negative pole of thebattery. As soon as the switch it is closed the circuit of the up magnetis closed at the said switch, and the elevator is made to travel upward,as above described, the circuit for the switch it through the saidmagnet being traced as follows: from the positive pole of the battery bywire 0, shaft a drum 0., cable aiwire 0 through the door, as described,wire 0 automatic switch, wire 0 cable a, wire a, contact member 0guide-bar 0 .wire 0 wire 7e contact-terminals 70 k wire In, rocker 7espring-arm k pin it, wire 7t, and wire (i to the yoke 19 of the upmagnet, thence through the magnet to the negative pole of the battery bywire I). As soon as the elevator has reached the landing b and the doorof the elevator is substantially opposite the door on the landing theroller e rides up the inclined side 36'and breaks the circuit of the upmagnet at the automaticallyoperated switch, as above described, therebystopping the car. At substantially the same time the fixed roller 70acts on the rocker 10 and turns the said rocker on its pivot, therebyremoving the spring-arm 70 from the pin 70 and breaking the circuit ofthe up magnet at that point also, and at the same time bringing thespring-arm k into engagement with the pin k Fig. 18, closing the circuitof the down magnet at the said pin and arm. As

soon as the rocker is turned on its pivot by the roller 70 the lever 75which has neviously engaged a projection 70 (see Fig. 17) on the cam andheld the same securely locked in its outer ordotted-line position, ismoved down by the lever 7e riding .up the inclined notch Z0 in the lever70", thus moving the end of the lever ICES down out of the path ofmovement of the projection 712 and permitting the lever 76 to be movedinto its normal or full-line position. Vith the rocker 70 moved into itsdotted-line position, and with the spring-arm 70 in contact with thestud 10 the circuit of the down magnet alone is closed, and the saidcircuit is closed at all the rockers below the third floor, so that ifthe switch 7c at either the first or second floor should be closed theelevator will be moved downward.

As shown in Fig. 1, only the rocker k on the first floor is shown inposition to close the down magnet I), so that if the switch 7c on thefirst floor (marked L) should be closed the down magnet will beenergized and the elevator brought to the first floor.

The circuit of the down magnet through the switch on the first floor maybe traced as follows: from the positive pole of the battery by wire 0,shaft a drum a, cable aiwire 0 through the car-door, as described, wire0 automatic switch, wire 0 cable Ct, wire contact-arm e guide-bare, wire0 wire 70 terminals 7e 7e ,wire 7e rocker 75 spring 0 pin k wire le andwire (i to the yoke 11 of the magnet, thence through the magnet I) tothe negative pole of the battery. As soon as the switch 70 on the firstfloor is closed and the magnet Z2 energized the armature b, Fig. 3, ofthe said magnet is attracted and the circuit of the magnet I) ismaintained closed, as above described. The roller k on the downwardmovement of the elevator acts on the rocker W at the third and secondfloors and moves them from the position indicated by dotted line in Fig.18 to their full-line position, closing the circuit of the up magnet atthe spring-arm 70 and pin is.

As soon as the elevator in its downward passage has reachedsubstantially the bottom of the elevator-Well, and the car-door is substantially opposite the door at the first landing, the circuit of thedown magnet is broken, as herein shown, by the insulated strip (1 andthe down magnet B is deniagnetized and the belt a placed in contact withthe loose pulley a; The circuit of the up magnet at the top of theelevatorwell maybe broken in a similar manner by the insulated strip din the guidebar (1 when the elevator is at the topof the well.

From the foregoing description it will be seen that by means of myinvention the elevator-car may be started and stopped not only on thecar itself, but also from any desired point or station in the travelofthe caras, for instance, at any desired landing. Fur thermore, it willbe noticed that the car automatically operates a switch at the landing,which switch is shown in the present instance as a rocker, so that thesaid car in its travel by a landing in either direction leaves the saidswitch in such position as to close the circuit at the said switch ofthe magnet necessary to be operated to bring the said car to the desiredlanding or station. This is especially advantageous in apartmenthotels,as the elevator can be run without the employment of an attendant in thecar.

I have thus far described my invention as employed to control themovement of an elevator-car; but I do not desire to limit my inventionto this use, as it may be employed to control the movement of any formof car or carriage or other movable bod y--su eh, for instance, as shownin Fig. 19, wherein is represented a car-truck having its axles m mmounted on wheels at, running on a track m On opposite sides of thetrack are located conductors m" m, the conductor in, as herein shown,being connected to one pole (as the positive pole) of the battery bywire in, the other conductor m being connected to the negative pole ofthe battery by wire m which is shown as broken and connected torail-sections m m", on which run wheels m 921 of a door, the said wheelsbeing joined by wire in in a similar manner to the rail-sections on theelevator-car. The axle m is electrically divided, as by insulationm,into two parts, (marked '70 71,) and the axiom is electrically dividedin a similar manner into two parts 72 73. The car is driven by a motor mherein shown asa compornnbwound electric motor, one wire m beingconnected to one coil 81 of amagnetm and the other wire on beingconnected to one coil 80 of themagnet m The magnets m m as shown, have acommon armature on. The motor has its armature-shaft provided with theusual commutator and brushes at 972 the brush M being connected incircuit with the field-wires m" m of the motor, and the brush 771 beingconnected by wire m with a current-collector m co-operating with theconductor m The armature-shaft, as shown, is provided with a pinion m inmesh with a gear at 011 the axle m. The axle on has mounted on it apinion a, connected, as shown, by intermediate gears to a large gear a,constituting a brake-gear, with which co-operates a pawl n forming thearmature of a magnet 11 having one ot' its wires a connected to acurrent-collector 7Z5, co-operating with the conductor m, the other wirea of the said magnet being connected to member a of anautomaticallyoperated switch, similar to the automaticallyoperated'switch on the elevator-car, the other member 91, of the said switchbeing connected by wire n to one coil, as 7 9, of the magnet m, and thewire a is connected to the coil, as 76, of the magnet M by branch wire77. The

wire a is connected by wire 01 to a switch provided with twocontact-teri'ninals n a, co-operating with contact-terminals n a, theterminal a being connected by wire n to the part "2 of the axle m, andthe termi nal 72" to the part 73. of the said axle by wire '72". Thewire a is connected by wire a to the coil 80 of the magnet 072. and thewire a is connected by wire 92? to the coil 81 of the magnet m Forpurpose of illustration let it be supposed that when the magnet nz isenergized the motor will propel the car forward or in the direction ofarrow 100, and that when the magnet m is energized the motor will movethe car in a direction opposite to that indicated by the arrow 100. Letit be supposed that the operator desires the car should move forward orin the direction of arrow 100. In this case the switch on the car isoperated to bring the terminal a in contact with the terminal 71 therebycompletingthe circuit of the coil 81 of the magnet miwhich circuit maybe traced as follows, viz: from the positive pole of the battery by wirem, conductor m, collector m wire on to brush 011 through the armature,thence by brush m through the field-magnet wire m" through the coil 81,thence by wires n a" to the terminals n a, thence by wire n to theautomatic switch a 017, thence by wire 92, through the magnet a, wire72', to collector or, through the conductor m wire m railsection m,wheels m wire m wheel 771 rail-section m to the negative pole of thebattery.

As shown in Fig. 19, both of the doors 0 0' are closed, and the circuitof the motor is complete and the said motor moves the car forward.

As soon as the operator in the car has completed the circuit of themagnet-coil 81, as described, he may break the said circuit bywithdrawing the terminal a from the terminal n; but the circuit of themotor is still maintained closed through the armature and the coil ofthe magnet m, the said armature being broughtin contact with the core ofthe coil 79, to which the wire a is connected, or, as it is technicallyknown, is grounded.

The circuit may now be traced as follows, viz: from positive pole of thebattery by wire m conductor m, collector m wire of, through thearmature-wire m, contact-stud 90, to which the said wire is connectedand with which the armature is brought in e'ontact, through the armaturem coil 79, wire '12, switch 11 of, wire a, magnet 91, wire 02 tocollector or, through the conductor in, wire of, and doors 0 o to thenegative pole of the battery. The car continues to travel forward untila projection carried by the ear and indicated by dotted lines 50, andwhich may be similar to the projection e 011 the elevator-car, as shownin Fig. 6, is struck by a stud or projection 0 located, as shown,between the rails of the track, the said stud acting on the projectionon the car to open the automatic switch, and thus break the circuit ofthe magnet-coil 79, and thereby stop the car, the circuit of the motorand magnet 97. being thus broken. As soon as the circuit is thus brokenthe armature a is moved away from the pole'of the magnet 02 either by aspring (not shown) or by gravity, or in any other usual manner, and thepawl n on the said armature is brought into engagement with thegear-wheel 02, thus stopping rotation of the axle m.

If it is desired to make the car travel in the direction opposite tothat indicated by arrow 100, the terminal a will be brought in contactwith the terminal a and the circuit of the coil 80 of the magnet 112closed, thereby moving the armature m into contact with the core of thecoil 76 of the magnet on, and also in contact with the stud 91, to whichthe wire m is connected, the circuit of the motor being maintainedclosed, through the coil 76, after the circuit of the coil 80 is brokenon the car at the terminals a n.

The circuit of the coil 80 may be traced as follows, viz: from thepositive pole of the battery by wire on, conductor m, collector and,wire 077?", through the armature to brush m, thence through field-magnetwires on, coil 80, wire at, terminals n at, wire it through automaticswitch, magnet 07?, wire a collector a, conductor m, to the pole of thebattery, as above described.

The circuit of the coil 76 may follows, viz: from the positive pole bywire m", conductor in, collector m wire m through the armature, wire on,stud 91, armature m coil 7 (3, wire n, automatic switch, magnet 41 tonegative pole of the battery, as described.

As thus far described the movement of the car is controlled from thecar; but it may also i be controlled from different points or stationsalong the track, which stations may be supposed to be located at thedoors 0 0'.

Each station will be provided with a switch, preferably a push-buttonhaving terminals 19 p, co-operating with terminals 13 p and at eachstation will be located a device substantially such as is located ateach landing of the elevator-well, which device will preferably consistof the magnet 70 controlling the cam 70 having attached to it thearmature 76 and by which the car is automatically stopped at the stationat which the magnet 70* is energized, the said armature and cam beingnot shown inFig. 19. One terminal of the switch, as 19 will be connectedto the rocker 7e co-operating with the terminals 70 k, by which thecircuit of that magnet on the car necessary to be energized to bring thecar to the said station is placed in proper condition, so that the saidcircuit will be completed when the push-button or switch at the stationis operated.

In practice the magnet 70 and the rocker 0 will preferably be containedin a box similar to that shown in Figs. 17 and 18, and will be locatedbetween the tracks m", so as to operate upon the projection on the underside of the car-brake and the automatic switch, while the rocker k isoperated upon by another projection 00 on the under side of be tracedas,

the car, as indicated by dotted lines, Fig. 19, which projection issimilar to the projection on the elevator-car.

At each station a bell p preferably located, the bell at one stationhaving one wire, as 1), connected to one of the wheels, as m of thedoor, and its other wire connected to a contact piece or arm 19",extended from the door and adapted to co-operate with a similar arm 19connected by. wire 1), as shown, to the terminal 13 of the push-bottom.The wire 19 of the bell at the station 0 is connected to the wheel m ofthe door. of the battery has connected to it a branch wire p (shown bydotted lines in Fig. 19,) and to which is connected the terminals p ofthe switches at the different stations. The magnet k which is indicatedin the diagram, Fig. 19, by a circle, has one wire connected to theterminal 19, and the other wire 19 of the magnet at the station 0 isconnected to the wire m while the wire 19 of the magnet located at thestation 0, is connected, as shown,

to the wire p joining the rail-sections m m" of adjacent doors. Theterminals 17 of the switches at adjacent stations are connected by wire19". lVhen the door of a section or station is open, the circuit of thebell at that station will be completed when the switch or push-button atanother station is operated. For instance, let it be supposed that thedoor 0' of the station is open and that the operator at the station 0wants the car. In this instance the operator closes the switch orpushbutton p, which completes the circuit of the bell 19" at the station0, which circuit may be traced as follows: from the positive pole of thebattery by wire 19 to terminal 19 of the switch or push-button at thestat-ion 0, thence by terminal 19, wires p p to contact-arm 19 throughthe bell-wire 17 rail-section m wire 19 through the door 0 and negativewire m connected thereto to the battery. The ringing of the bell at thestation 0 notifies the operator or attendant at that station that thecar is wanted at some other station, and gives notice to him that hisdoorinust be closed in order to complete the circuit of the magnetswhich control the movement of the car.

The operation of the car as shown in Fig. 19 is identical with theoperation of the elevator-car shown in Fig. 1, and the manner ofcontrolling it both from the car itself and from the different stationsis identical.

In Fig. l I have shown and described the electro-inagnets as controllingthe operation of a belt-shifter by which the elevator-car is raised; butI do not desire to limit my invention to this particular class ofmechanism for actuating the elevator, as other forms may be used-such,for instance, as shown inFig. 20, wherein the electro-magne-ts controlan electromotor 8, having in circuit with it a resistance s, by whichthe excessive current on The positive pole ing of the elcvator-car-isprevented from burning out or otherwise injuring the motor,

the movement ofrthe resistance-lever .9 being controlled by a solenoid 3having connected to its core a piston of a dash-pots", which latter alsoobviates the starting of the car with a jerk.

As shown in Fig. 21, the electro-magnets D b are connected to andcontrol the circuits of solenoids .5, having, as shown, a common core 5which, as herein shown, is connected to a valve 8 controlling the portsof a cylinder in which is reciprocated a piston s", having itspiston-rod 8 connected in suitable manner to the hoisting mechanism orto a main valve. So, also, the magnets U I) may be connected to acompound-wonnd solenoid s, Fig. 22, having its wires 8 8 connected to acompound-wound motor 3 having its armature-shaft 5 connected by belt 5"to a pulley on a shaft s, provided with a worm s somewhat similar to theworm shown in Fig. 3. The solenoid s has a core 8 having an arm 8 towhich is secured a belt-shipper 3 provided with teeth or serrations 5which are brought into engagement with the worm .9 when the solenoid sis energized, which occurs when the circuit of either of the magnets Z)Z) is closed.

When one magnet, as b, is energized, it attracts its armature, closesthe circuit of one coil of the solenoid which revolves the armature ofthe motor in one direction, thereby revolving the shaft .9 in onedirection, and through the teeth .9 011 the shipper 3 moves the beltfrom the loose pulley s to a fast pulley, as 5 producing travel of theelevator in one direction, and when the magnet I) is energized thecircuit of the coil of wire 5 of the solenoid and motor is completed,and the shaft .9 is revolved in the opposite direction and the beltshifted to the fast pulley 5 causing the tavel of the elevator in theopposite direction.

Instead of the particular form of selecting device shown in Figs. 1, 8,and 9, I may employ any other form of selecting device-such, forinstance, as shown in Figs. 1* and 15, wherein the pointer (Z is mountedon the arbord', extended through a disk or dial 6', provided withnumbers indicating the different stations. In this instance twopush-buttons of ordinary construction are employed, as the switches d d.
